IMPROVEMENT IN TREATING PETROLEUM AND OTHER OILS T PRODUCEA'V EI-HCLE FOR PAINTS AilD VARNISHES.

'' specification forming part of Letters Patent No. 36,419, dated September 9, 1862.

To all where it may concern:

Be it known that I, ANTQNIOKMEUGCI, of idlii'to'n, in the county of Richmond-and State of New York, have invented a new'and Im-- "proved Process for Preparing Hydrocarbon when mixed with paints, act as'thi'nners and driers, the same as turpentine. The invention consists in treating petroleurn, coal-oil,or other hydrocarbon liquids or oils with hfyponitric gas, substantially in the manner hereinafter described, for the purpose of rendering said oils siccatire and fit to be used in paints. y it also consists in mixing with petroleum,

' he same has been cakes obtained in the manufacture of linseedoil or of fariua of linseed, together with acertain quantity. of fish oil, for thopurpose of giving to said liquids to required consistency for painting purposes.

' To enable those skilled "n the art to fully understand and use my invention, I will proceed to describe it. 4

The petroleum *or other oil to betreated with hyponitric gas is put in a vessel which communicates by a suitable pipe with a balloon or retort of glass or other'suitable material, in which the hyponitric gas is produced. The preparation of the hyponitric gas can-be eflooted by chargin gsaid balloon or retort with three (3) parts of nitric acid to one (1) part of starch, and heating it slowly with steam or in any other desirable manner. a After the oil has been exposed to the current of hyponitric gas for about two (2) hours it assumesa dark-green or a reddish-yellow color, which indicates that the operation is finished. The oil must now be repeatedly washed with clean water until is accomplished the oil isheated in a suitable vessel or still by means of a steam-coil or in any other desirable manner for the purpose of expelling the water. By this process petro tago in points. After I have treated the petroleum orbther oils with hyponitric acid, and

I add to eachone hundred (100) gallons of said oils about fifty (50) pounds of linseed or frour .(150) p 'ounds of linseed cakes, (obtained in the manufacture of linseed oil,) and from twenty t 'twentyhve gallons of fishoil, heating the mixture to about 150 to 200 Fahrenheit for from six (6) to eight (8) hours,

rest the oil is drawn ed" and the residue is pressed. The oil obtained by this process can be used with advantage for paints. It is very cheap, it has'abody equal to lins'eed-oilor nearly so, and it dries in ashort time.

Having thus fully described my invention,

Letters Patent, i

in treating petroleum, kerosene, or other oils, substantially in the manner and for the-purpose described.

- 2. Mixing petroleum or other oils after they have been exposed to'a current of "hy'ponitric acid, as described, with linseed or with linseed cakes and 'fish-oil, substantially in the-manner Asronio Mnuoor.

all traces of the acid disappear, and after this,

lenm, kerosene, or other oils are rendered 'sicnative, and they can now be used with advanin order to increase their consistency or body one hundred to one hundred and fifty I andstirring it well during the whole operation. It is then left to stand, and aftcralong what I claim as new, anddesire to secure by 1. The employment or use of hyponitric acid and about in. the proportions herein specified-
